“…This has been achieved previously for step-index polymer fibres by adding a highly nonlinear dye to the polymer preform before drawing it into a fibre. 19,20 The dye was added to the monomer during polymerisation. The chemical processes required for the polymerisation can be avoided by instead solution doping the polymer.…”

We demonstrate dispersion-engineering of microstructured polymer optical fibres (mPOFs) made of poly(methyl methacrylate) (PMMA). A significant shift of the total dispersion from the material dispersion is confirmed through measurement of the mPOF dispersion using white-light spectral interferometry. The influence of strong loss peaks on the dispersion (through the Kramers-Kronig relations) is investigated theoretically. It is found that the strong loss peaks of PMMA above 1100 nm can significantly modify the dispersion, while the losses below 1100 nm only modify the dispersion slightly. To increase the nonlinearity of the mPOFs we investigated doping of PMMA with the highly-nonlinear dye Disperse Red 1. Both doping of a PMMA cane and direct doping of a PMMA mPOF was performed.Keywords: Microstructured polymer optical fibre (mPOF), dispersion engineering, influence of loss on dispersion, dye doping, poly(methyl methacrylate) (PMMA), Disperse Red 1

“…The remaining water is removed by adding suitable drying agents such as CaCI 2 • The monomer is purified by distillation under reduced pressure. The preform for flber fabrication is [34] made by polymerizing the purified MMA. The monomer is mixed with benzoyl peroxide (0.01 M) as initiator, n-butyl mercaptan (0.03M) as the chain transfer agent along with Rh 6G and Rh B in sealed tubes.…”

Multimode laser emission is observed in a polymer optical fiber doped with a mixtnre of Rhodamine 60 (Rh 60) and Uhodamine B (Rh B) dyes. Tuning oflaser emission is achieved by using the mixture of dyes due to the energy transfer occurring from donor molecule (Rh 6G) to acceptor molecule (Rh B). The dye doped poly(methyl methacrylate}based polymer optical flber is pumped axially at one end of the fiber using a 532 nrn pulsed laser beam from a Nd:YAG laser and the fluorescence emission is collected from the other end. At low pump energy levels, fluorescence emission is observed. When the energy is increased beyond a threshold value, laser emission occurs with a multimode structnre. The optical feedback for the gain medium is provided by the cylindrical surface of the optical tiber, which acts as a cavity. This fact is confirmed by the mode spacing dependence on the diameter oC the tiller.

“…Nonlinear optical (NLO) properties of molecular materials have attracted considerable attention because of their potential application in optical fibers [1], data storage [2], optical limiting [3], optical computing [4], optical switching [5], signal processing [6], etc. Compared with conventional inorganic crystalline materials, organic NLO materials have some advantages, including facile processing and reduced production cost, lower dielectric constants, and higher electro-optic coefficients et al In the past two decades, much effort has been devoted to develop organic second-order NLO materials.…”
